Scientific Visualization
Please note that there are no more vacancies for this course. Video recordings will be made available on this page post-event.
The Swiss National Supercomputing Centre (CSCS) is pleased to announce the online course "Scientific Visualization," which will be held from October 12 to 13, 2020 (CEST Timezone).
Course Description
This online course serves as an introduction to general topics in 3D Scientific Visualization available on Piz Daint. We briefly introduce several well known stand-alone OpenGL applications. For the remainder of the presentations, we then focus on the use of Jupyter notebooks (JupyterLab) available at CSCS and on the ParaView application. We discuss common data formats and how to import data into ParaView.
We present standard visualization algorithms for 3D scalar and vector fields and demonstrate two Jupyter-based widgets for ParaView rendering and polygonal and volume rendering (ipyparaview and itkwidgets). Finally, we present and demonstrate photorealistic rendering in ParaView (desktop and JupyterLab).
Handouts will be distributed in the form of ParaView Python scripts and Jupyter notebooks.
Target Audience
CSCS users wishing to create data visualization with a mix of Python programming and ParaView application. For the most part, we will do visualization on a single-node with multi-core and/or GPU acceleration.
Participants are required to have basic familiarity with JupyterLab at CSCS (jupyter.cscs.ch) and a local desktop installation of ParaView (www.paraview.org).
